Hi all, just got here . Ok I have some problem atm with my 5xcory cat they r currently housed in an 25g tank with 11 neon/cardinal tetra alone with 3 baby angle, a pleco, and an oto cat. The water stats of the tank is following:
80-82f due to room temperature
ammonia=0
nitrite=0
nitrate=arround 10
ph=8(cant do much for this one cause water in my area is kind of high and I dont like adding chemical at all so rather let it be)
Its a planted tank with a driftwood and some non sharp gravel.
All of them just laying there under plant or behind driftwood etc for all day and some time swim to different spot. But dont seem to be very attive in those from my LFS. Any one knows why?
At the moment, the reason i'd most probably go with is your pH value. Most, if not all corys prefer a pH value of neutral (7) or slightly acidic (6-7). A pH of 8 means alkaline water, which probably means not the best/ideal water conditions for it...so maybe thats why they are constantly hiding, and are not displaying their best colours.
I speak 12 languages fluently. English is my bestest. - Bush
What species of Cory are they, some just don't like the water that warm, but there are a number of species that would just love those higher temperatures.
40g tank with 4 diamond discus
25g tank with 14xcardinal/neon tetras and 5xangle fishs
20g pure planting tank with 5 cory cats
75g tank with 6 x altum angels
10g tank with a small feeder and 1 small pleco
150g tank with 13 clown loaches
- Please be careful with the addition of rainwater. Rainwater has no buffering capacity (that is, it has no chemicals which can help to stabilize pH). If your tap water has low buffering capacity, you could subject your fish to big swings in pH. I know it's usually assumed that water with a high pH has high hardness, but this is not always the case, particularly if you use a water softener (which can leave you with alkaline water with NO buffering capacity). Before you start playing with adding rainwater, etc, my advice would be to test for carbonate hardness and make up test batches of water so that you get the pH/kH that you desire.
- If you're going to change the pH, please do so gradually, particularly when you're going from higher to lower pH. I wouldn't go more than a change of 0.1 or 0.2 per day - others may have different rules of thumb to share.
- My cories seem to like it if I set up the tank with densely planted hiding areas and/or overhangs on each end and an unobstructed free-swim space in the middle.
- If you've not had these for very long, give them 2-4 weeks to get settled in and start acting "normal".
- There are different kinds of "active" with cories. "Good" active is foraging behaviour and when the fish are resting, they usually have the dorsal fin erect. "Bad" active is more frantic, and when the fish do rest, they don't have the dorsal fin erect. So, there's always the possibility that the fish are happier with their setup now than when they were in the store...
Is this a 25 gallon tall? If so, the Cories will have little space on the bottom. The undefined "Pl*co" will most likely take over the small bottom territory. The Cories won't have anyplace to go but all over the rest of the tank. The three Angels have probably taken over the rest of the tank. Add the driftwood and the plants and it sounds as if your tank is a bit overcrowded! No room at the inn.
My old 25g seems to be fine for them just they dont act very attive and its planted and have driftwood so hidding place is not a problem. But any ways they now been remove alone with albino cory I got from fish store into a new 10g I got for them. They seems to be alittle more attive now as by tomorrow my small driftwood will be ready for them .
